From 6a278369c05a298a4367306d986467a9ceacae8c Mon Sep 17 00:00:00 2001 From: Raul Fernandes Date: Tue, 30 Jul 2013 09:26:05 -0400 Subject: EXA/6xx/7xx: optimize non-overlapping Copy In case dst and src rectangles of a Copy operation in the same surface don't overlap, it is safe to skip the scratch surface. This is a common case. Based on evergreen/ni patch from Grigori Goronzy.
